If you thought you'd seen some racy bikinis this summer, brace yourself.

A string-thin 'bikini' is taking the internet by storm having just landed in Japan as it's hailed the hottest new piece of swimwear in the Far East this summer.

The two-piece, by fashion house Buyma, lets wearers show a very generous amount of 'under-boob' and just about covers their nipples.

Quite how this would go down on Bournemouth beach, we don't know.

Not only does the bikini top not encase the wearer's breasts properly - like a bikini is supposed to - but it features a lot of unnecessary criss-cross straps across the chest and cleavage - as if to accentuate its lack of support in other, more vital areas.

Women in Japan are snapping up the bondage-inspired swimsuits from Pocket Tokyo, where it retails for around £28.

The item comes with optional black thigh-high socks to complete the 'sexy' look.

Despite the crazy tan lines it no doubt creates, the racy two-piece is the latest fashion statement taking the country by storm.

Rocket24 explained: 'It is a design that only the bravest of the brave would dare to wear down at the beach this summer. The perfectly placed cut-outs are designed to show off feminine curves.

'All those revealing cut-outs would probably get us arrested for public indecency down at the beach, but we can't help but think this would be much better suited to someone who's already proven themselves when it comes to pulling off unusual outfits.'
